SPRAYER.

Specification of Letters Patent.

Patented A r. 19, 1910.

Application filed February 9, 190B.- Serial No. 476,870.

To all whom "it may concern:

Be it known that I, \VILLIAM H. IRELAND, a citizen of the United Verndale, in the county of \Vadena and State of Minnesota, have invented a new and useful Sprayer, of which the following is a specification.

It is the object of the present invention to provide a spraying mechanism which is to be supported upon the tongue or other convenient part of a cultivator and which will operate to spray, with insecticide, the plants being cultivated and one object of the invention is to so construct the device that the volume of liquid discharged will be constant.

It is a further object of the invention to keep the liquid being sprayed, in a constant state of agitation so that the liquid discharged from the sprayer Will be of a constant and unvarying strength.

i still further object of the invention is to provide a means for permitting the escape of air from the container of the device as soon as the air pressure within the container has reached a predetermined degree, and in making this means adjustable so that by its adjustment, the spray may be discharged with greater or less force.

In the accompanying drawings, Figure l is a side elevation of the fore part of a cultivator of the ordinary type showing the sprayer device embodying the invention mounted thereon. Fig. 2 is a rear elevation of the said portion of the cultivator and the sprayer device. Fig. 3 is a vertical transverse sectional view through the sprayer and pump of the sprayer on the line 25 3 of Fig. 1, and Fig. 4: is a view showing a slightly modified form of sprayer ('lischarge.

In the drawings, the axle of the cultivator is indicated by the numeral 5. the ground whccls by the numeral (3, and the tongue by lhc numeral 7. A sprocketgear 8 is either clutchcd or permanently connected with one of thc ground wheels (3 so as to rotate therewith and trained about this gear and a sprocket gear 0 at one end of the shaft 10, is a sprocket chain 11. The shaft .10 is in the natureof a crank shaft and is jonrnaled in States, residing at bearing openings in the upper ends of upwardly directed bracket arms 12 which are secured to and supported by the tongue 7, the crank portion of the shaft being located between the bracket arms as is clearly shown in Fig. 2 ot' the drawings. The functionof this shaft will presently be made clear.

tank 14 and the opening in this stuffing box alines with an opening in a bracket 17 also secured upon the said end of the tank, and

mounted to reciprocate through the open ings in the stuffing box and bracket, is apiston rod 18 carrying two perforated heads 19, the-perforations in the heads being indi catedby the numeral 20. These heads are preferably of sheet metal or thin plates of cast metal and it will be understood that upon reciprocation of the piston rod 18 and its heads 19, the fluid within the tank Will be tl'iorougl1l agitated and as a result, all portions thereof, will be of the same strength, or in other Words will contain approximately the same percentage of paris green or other insecticide employed.

The straps 13 in addition to supporting the tank 14 upon the tongue 7, serve to support av pump cylinder 21 upon the upper side of the tank lat and working in this pump cylinder is a piston 22 the rod of which is indicated by the numeral 23, the rear ends of the piston rods 18 and 23 being connected as at 2t so that they will reciprocate in unison.

In order that such reciprocation of the rods- 18 and 23 may be had during the travel of the cultivator. av connecting rod 25 is connected at one end to the connection 2d between the two rods 18 and 23 and at its rear end to the crank portion of the shaft 10 so that. upon rotation of this shaft. reciproca tory motion will be imparted to the two piston rods [8 and 23.

A chock 'alvc 2t) is providcd at one end of the pump cylinder 2] and leading from the forward end of the pump cylinder and communicating with the forward end of the tank 14 is an air conducting pipe 27 which serves to convey the air under prcssurc from the pump 21 to thesaid tank. valvc 29 is interposed in the pipe 27 at some convenient point and this valve may be ndjnslcd so that upon a certain prcdctcrlnincd pressurc. being reached within the tank H. the valve will open to permit cscapc of tho air until the desired degree of lJlt? Hlll'( is H.-

cured. As will be shortly described, the

from the nozzle will be quite strong and forcible but that on the other hand. if the valve is adjusted so that upon a eoinpar' lively low degree 0]. pressure being reached in the tank 14, it will open, a comparatively weak stream or spray will be discharged 1 from the tank.

The discharge mentioned above 1S eonducted through a pipe 29 which leads from the rear end of the tank 14, downwardly, and terminates in a valved coupling 30. De- 1 i as .my own, I have hereto atfixed my signatachably connected to the pipe '29 through the instrumentality of this coupling 30, is a pipe 31 having a spray nozzle or d scharge 32 which has its perforated area presented 'lhe'valve in the conpling 30 f is of the cut-oft type so that the supply of downwardly.

fluid may be cut off when desired,

In the form of the invention. shown in Fig. 4: of the drawings, the pipe 31. has several hl'anches 33 each having a spray nozzle 3-1- and the (.lisrharge shown in this form of the invention is of course adapted for use in spraying several rows of plants at a time.

\Vhat is claimed is:

In a sprayer, a container, a rod mounted to reciprocate in said container, perforated agitator heads carried by the rod, a pump cylinder, a pi peleading from the cylinder to the container, a safety valve interposed. in said pipe, a piston working in said cylinder, a rigid connection between the rod and the piston, a crank shaft. and a connecting rod pivoted to the crank shaft and to the rigid connection between the piston and rod.

In test-nnony that I clann the foregoing ture in the presence of two witnesses.

WILLIAM H. IRELAND.
